broken away to more clearly disclose the form;

and disposition of certain interior parts. Fig. 2 is a horizontal section of same on the line 2 2 of Fig. l. Fig. 3 is a vertical section on the line 3 3 of Fig. 2. Fig. 4 is a detail View looking from the side of the register opposite to that seen in Fig. 3 and illustrates l[he positions assumed by certain parts of the register upon the depression of a finger-lever. Fig. 5 is a view similar to Fig. 3, one of the fingerlevers being depressed and the cooperating parts being shown in the positions that they assume as a result of such depression of t-he finger-lever.

Similar reference -,numerals denote like parts throughout the several views.

This invention relates to improvements in registration and indication devices, and particularly to that class of registration and indication devices commonly known as cashregisters.

The object of my invention is to provide a cash-register which shall be simple and cheap as regards construction, efficient in operation, and which shall embodyin its construction a till or drawer for coniainin g cash, mechanism capable of effecting continuons registration and indication of the cash contents of the till or drawer as the same may accumulate therein, and mechanism capable of effecting temporary indication of separate amounts of cash as the same may be added to the contents of the till or drawer, the said continuous-regis tration and temporary-indication mechanisms being adapted and arranged for joint operation through the depression of one of a series of actuating-levers.

My invention consists in the employment of certain novelly-formed parts, in the novel disposition and arrangement of the various parts,

in certain combinations of the latter, and in certain details of construction, all of which will be hereinafter specifically referred to.

Having reference to the accompanying drawings, 4L denotes the till-case of the regand construction. f

d is the upper portion of the till-case, and thereupon is firmly mounted a case 5, prefer-'- ably of metal, and the same serves to inclose the greater portion of the operative mechanism. The till-case is provided with a cashtill 6, the forward portion of which is nor m ally supported by parallel rollers 7 mounted to the base of the till-case. The till 6 carries rollers 8, preferably one at each lower rear corner thereof, which rollers under normal conditions rest upon the base ofthe till-case, and said till is further provided with rollers 9, preferably one at each upper rear corner thereof. Said rollers 9, however, are not in contact, normallywith the upper portion 4 of the till-case. The employment of rollers 7, 8, and 9 and in the manner set forth is essential in that during the operation of ejecting the cash-till from the till-case, as will be hereinafter explained, the forward portion of the cash-till rides upon the rollers 7, while the rollers S travel along the base of the till-case until the outer or forward portion of the cashtill overbalances the rear portion thereof, whereupon the cash-till rocks or tilts upon the rollers 7 in a manner that the forward end of said till descends and the rear end thereof ascends, with the result that the rollers 9 are brought in contact with the upper portion 4E of the till-case, and thereafter the cash-till au tomatically moves outward from the tillcase by reason of its own gravit-y until checked, as by the rollers 9 engaging the piece 4" of the till-case.

9 is a rigidly-disposed transverse shaft on l0 l0' 10, are mounted to rock or tilt. The depressible end portions of said finger-levers project outward from the shaft 9', (the front portion of case 5 being cut away, as shown, to admit of their so doing,) and each presents to the finger touch a broadened upper surface, upon Which are arranged numerical char acters, as l to 9, inclusive. There are ister, preferably of wood and comm on in forni to rotate in suitable bearing elements fixed.

which a suitable number of finger-levers, as

IOO

vfurther mounted to rock on the shaft il', one at each end thereof, radial arms 11 11', in the free ends of which is rotatably mounted or journaled a universal bar 12,which normally rests upon the finger-levers 10 10' 10". Centrally upon the bar 12 there is 'firmly mounted a drive medium 13, preferably in the form of a sprocket-wheel, and there are likewise mounted on said bar 12, one at each end thereof, cam-like parts 11 1-l-', each having a general convolute edge surface, divided, preferably, inte ten concentric steps or segments with radii varying accordingly, and which l shall hereinafter refer to as regulators7 15 is another rigidly-disposed transverse shaft,and thereon are rotatably mounted a series of con tinuous displajhdisks, as 1G 1o" 16" 16"', each of which disks bears numerical characters, as 1 to 9, inclusive, and a cipher. There are also rotatably mounted on the shaft 15 a series of toothed lock-wheels 17 17' 17" 17"', one

alongside of each display-disk, together with a series of toothed d rive-wheels 1S 18' 1S"1S"', one alongside of each loclewheel, and the groups of elements thus formed, each eom prising a display-disk, lock-wheel adjacent thereto, and drive-wheel adjacent to the lat ter, are respectively secured together, as by riveting, so that each group of elements rolates as a unit on shaft 15.

19 is a shaft arranged transversely within the case 5; but, unlike the shafts O' and 15, the shaft 19 is so supported at its ends by the respective sides of the ease 5 that a rocking motion may be imparted thereto. Shaft 19 carries a series of forwardly-projecting radial arms 2O 20' 20" 20"', one opposite each of the lock-wheels 17 17' 17" 17"'. Said radial arms are firmly mounted on shaft 19 and move in unison when shaft 19 is rocked, and said radial arms have pawl-like free ends adapted under certain conditions to simultaneously engage each one of the loclewheels 17 17' 17" 17". rlhere are further firmly mounted on shaft 19 rearwardlyeextending angular arms 21 21', one near each end thereof, and said arms comprise each a radial and a depending member. The last-named members of the arms 2]. 21' are provided with hook-shaped lower ends adapted under certain conditions to simultaneously engage the one the free end of radial arm 11 and the other the free end of radial arm 11'. The shaft 1.) also carries, one at each end thereof, radial arms 22 22',which project rearwardly from said shaft, the former over regulator 1l and the latter over regulator 14', and each is provided at its free end with a suitable contact-point, as 22", Fig. The upward rocking movement of shaft 19 is limited bythe inwardly-projecting steps 19' 19", which overlap the one radial arm 22 and the other radial arm 22', and the reverse movement of said shaft may be limited by like stops arranged to respectively underlap said radial arms. l further employ a series of sublevers, as 223 23' 223" 23"', within the ease and fulerumed at the rear end thereof, as at 2-1, from which point they extend forward and lie normally contiguous, one to each of the finger-levers 10, 10', and 10", excepting sublever 23"', to operate which no finger-lever is required, as will hereinafter appear.

ln conjunction with sublevers 223 23'23" I make use of a series of vertical racks 25 25' 25" 25"', which are pivotallyconnected one to the Afree end ofeach of said sublevers, and the same are respectively held to permanent engagement, one with each of the respective .drive wheels 1S 1S' 1S" 18"', by means of suitable elastic elements, as the springs 2G, Fig.

There are loosely mounted on the rigidlydisposed transverse shaft 27 a series of angular lock-levers 2S 28' 28" 28"', having pawllike upper ends adapted to engage each the teeth of one of the lock-wheels 17 17' 17" 17"' and lower ends suitably shaped to engage and under normal conditions support each the free end of one of the sublevers 23' 23" 23"', the latter being normally held yieldingly to contact therewith each by means of a spring 20, and each of said lock-levers is pro0 vided with a spring 27', the tendency of which is to so move the lock-lcver as to disengage the upper end thereof from the loclewheel when the corresponding sublever is raised. The sublevers 23 23' 23" are provided each with a lateral projection er pin 30, and, 'the fingerdevers 10 10' 10"are provided each with a vertical slot-like opening SO', the pin of any one of the sublevers named being adapted to project into or engage the slot-like opening in the adjacent ii nger-lever and in such manner that the sublever is caused to swing upward on its fulcrum when the forward end of the tinger-lever is depressed, and said opening 30' in the linger-lever is such as will permit a limited upward movement of the sublever without affecting the linger-lever, as will hereinafter more clearly appear.

Springs 31er the like are provided, one for each of the finger-hivers, and the same serve to return the linger-levers each to its normal position upon the same having been de pressed, as above stat l.

It will be seen that repeated depressions of any one of the finger-levers result in rotatable movement of thc corresponding displaydisk on shaft 15; but itis essential that means be employed whereby when, say, disk il() shall have thus been caused te make nearly one complete revolution the next disk 1G' will be urged along one degree in its rotary movement, and again when the disk 1G' shall have made nearly one complete revolution the next disk 1U" will be urged along one degree in its rotary movement, and so on throughout the entire series of display-disks. To this end the suhleverf' carries at its free end a vertical arm 32, preferably formed in tegral therewith, and this arm is provided at its npperend with an angular offset 32', which projects from said arm toward and terminates ITO at a point adjacent to the display-disk 16. A stop 34 is rigidly secured at its lower end to the upper portion of the till-case, projects upward therefrom, preferably at a slight forward inclination in the vertical plane of the end of the offset 32', and terminates at a point somewhat below said offset as the latter occupies its normal position. The disk 16 carries upon one side thereof and near its peripheral edge an angular gravity-catch 33, adapted to swing on a pivot, as 33', xed in said disk. One member of the catch 33 is heavier than the other and normally depends from the pivot 33', while the latter normally projects forward from said pivot in a substantially-horizontal plane. The location of the catch 33 with respect to the disk 16 is such that when said disk shall have reached a certain point in its rotary movement the depending and horizontal members of said catch will simultaneously engage, the former the upper end of the stop 34 and the latter the offset 32', with the result that upon said disk being urged further along in its rotary movement the sublever 23 will be swung upward on its fulcrum, and thereby cause by reason of the engagement of rack 25 with drive-wheel 1S the disk 16 to rotate forward on shaft 15 a definite degree or until such time as disengagement of the depending member of the catch 33 from stop 34 takes place, which necessarily follows as said catch moves along with the disk 16. Disks 16 16" carry the former a gravity-catch 35 and the latter a gravity-catch 36, which catches correspond in all respects with 33. Sublevers 23" 23" are provided the one with a vertical arm 35 and the other with a vertical arm 36', each of which vertical arms corresponds in all respects with arm 32, the one having an offset 35" and the other an offset 3G, each corresponding with offset 32. 37 37 are vertical stopseach corresponding in all respects with stop 34, and the former is designed for operation in conjunction with catch 35 and the latter with catch 36. Now when disk 16' shall have reached a certain point in its rotary movement the members of catch 35 simultaneously engage, the one the stop 37 and the other the oifset 35",with the result that upon disk 16 being urged further along in its rotary movement thelsublever 23 will be swung upward on its fnlcrum, and thereby cause by reason of the engagement of the rack 25 with drivewheel 1S" the disk 16 to rotate forward a definite degree or until disengagement of the depending member of catch 35 from stop 37 takes place, and the same effect may be had upon disk 16"' through like joint action of catch 36, stop 3U, sublever 23', and rack 25 engaging drive-wheel 18"', as will be readily understood. In this connection the object of the freedom of the sublevers to move upwardl'y without affecting the corresponding finger-levers, as hereinbcfore referred to, is apparent.

The case 5 is provided with aseries of openings 38 3S 33 33"', one opposite the peripheral surface of each permanent display-disk for exposing the characters thereon.

The upper portion 4' of the till-case is cut away, as at 3f), to admit of ample depression of the finger-levers, and said portion is furtherprovided with an opening 39' near its rear end.

40 is a wire frame hinged to the front of case 5 and normally sustained in a horizontal position by the vertical support 40', su rmeunted by the loop-shaped portion 40".

Vithin and at the rear end of the till-case there is disposed a yielding element, as the spiral spring 4l, which' is attached atits lower end to the base of the till-case and connected at its upper end with an adjusting medium, as the sprocket-chain 4l', which extends upward through the opening 39' and works upon a suitably-mounted idler 4l, extends from said idler to and works upon the sprocketwheel 13, and extends from the latter outward through the opening 2 in case 5 through the loop-shaped portion 40" and has attached to its outer end a finger-piece 42, preferably in the form of a ring.

42" is a finger-key mounted on a vertical stem 43, which extends downward through a suitable opening formed, preferably, in iinger-lever l() and is capable of an upward and downward movement within said opening independent of the finger-lever, said upward movement being limited by a stop or collar 43, fixed on said stem below the finger-lever. rFhe lower end of the stem 43 engages the for- 'ward end of tilting lever 43, disposed to work on pivot 44. The stem 43 is held normally at the limit of its upward play through the medium of lever 43", in conjunction with spring 44' or like element, the tendency of which spring is to depress at all times the rear end of lever 43", and while so depressed the same serves to engage the rear end portion of cash-till 6 or a suitable projecting part,

as 6', secured thereto, and thus lock the cashtill against ejectment or withdrawal from the till-case.

45 is a rigidly-disposed shaftarranged transversely within the upper portion of ca se 5. There are mounted to rotate on said shaft a series of temporary display-disks 46 46 46, each carrying upon its peripheral surface numerical characters, as l to 9, inclusive, and a cipher. There are further mounted on said shaft 45 a series of pinions 47 47', one alongside of and secured to cach of said disks and adapted to rotate therewith. There are formed in the upper portion of case 5 aseries of openings, one opposite the peripheral surface of each of the temporary display-disks, for disclosing the characters thereon.

43 43 4S" are vertical gravity-arms, each weighted at its lower end, and said arms should be so connected, one to the distant end of each of the iinger-levers 10 lO' l0", that while any one of the linger-levers may serve upon its outer end being depressed, as here- IOO IIO

fi e-iaoie inbefore explained, to lift the arm connected therewith to any point in its upward movement the linger-lever may return to its normal position without otherwise affecting said arm. To this end I provide the gravity-arms named each with a longitudinal slot-like opening 49. The linger-levers 10 10 10 are provided with lateral projections 50 50 50", one at the distant end of each Iinger-lever. The lateral projection of any one of the linger-levers engages the slot-like opening in the gravity-arm designed for operation in connection with said lever, and said projections may comprise suitably headed and threaded screws adapted to be passed one through the slotlike opening in any one of the gravity-arms and screwed into a suitably-threaded opening in the distant end of the corresponding iinger-lever. Each of the gravity-arms terminates at its upper end in an elongated eye, as 5l, adapted to surround the corresponding` pinion in the series 47 i7', and each has internal teeth on one side adapted to mesh with the teeth of the pinion it surrounds, and this to the end that upon movelnent being imparted to any one of the gravity-arms in an upward or downward direction the corresponding temporary display-disk may be rotated accordingly. Any undue tilting or lateral movement of the gravity-arms as they ascend or descend may be obviated by the employment of guides, as 5l/, one for each gravityarm. The gravity-arms are each provided with a series of notches at a suitable point in the rear edge thereof, and a series of springcatchcs 52 are secured interiorly to the rear end of the till-case, one opposite each gravity-arm. Said catches have at all times a tendency each to engage at its upper end one of the series of notches with which the gravity-arm adjacent thereto is provided.

53 are angular releasing devices comprising each a horizontal member and a depending gravity member and pivotally disposed along the rear end of the cash-till G, one opposite each spring-catch 52. The devices 53 serve to simultaneously release each the spring-catch opposite thereto from engagement with the notched rear edge surface of the adjacent gravity-arm by reason of the lree or distant end of the horizontal member of said releasing device engaging' said springcatch when the cash-till 6 is closed, and in the event that any one of the gravity-arms shall have been raised and locked in an elevated position such disengagement of the corresponding spring-catch permits said arm to descend, in doing which the lower end thereofrengages the horizontal member of the releasing device, causing the latter to swing on its pivot in a manner that the horizontal member thereof is depressed and the springcatch is permitted to reengage one of the notches in the gravity-arm. The releasing device automatically returns to its normal position upon withdrawal of the cash-till from the till-case and through the action of its depending gravity member.

For the purpose of imparting an initial impetus to the cash-till when the latter shall have been unlocked, as hereinbefore explained, I provide a series of upright leal'- springs 54, the upper ends of which lie against the rear end portion of said cash-till and tend at all times to urge the till outward.

It will be understood that disk 1G represents units, disk 1G tens, disk 16 hundreds, and disk 10 thousands.

The operation of my improved register is as follows: Assuming that one or more units or cents are to be placed in the cash-till, the user grasps linger-piece 112, draws chain Ai1 outward, and carries and holds the lingerpiece over the character on lever 10 which represents the number of units or cents he wishes to place in the cash-till, whereupon he depresses lever 10. In thus drawing the chain 4l outward the universal bar 12 is rotated forward in its bearings, and the regulators 1-1- 14;' are consequently adjusted so that the corresponding steps or segments of said regulators are uppermost, and the depression of the linger-lever results in an upward movement of the universal bar 12, which takes with it the radial arms 11 ll' and also said regulators, at the same time sublever is swung upward on its fulcrum, at the outset of which upward movement of said sublever the angular lock-lever 2S, through the action of spring 27', disengages lock-wheel 17, and through the engagement of rack L5 with the drive-wheel 18 a forward rotary movement is imparted to disk 16, which continues till the character thereon which corresponds with that over which the linger-piece 12 is held appears at the opening 38, whereupon the regulators '1t lil' in their upward travel will have respectively lifted the radial arms 2; 22', thereby imparting a corresponding roekiug movement to shaft 1D, with the result that the pawl-like end of radial arm 20 engages the lock-wheel 17, thus locking said disk against :further movement. The extent to which any one of the linger-levers may be depressed is determined by the extent of the radial dimension of each of the parallel regulator-segments that may be uppermost. For instance, when those segments having each the least radial dimension are uppermost the depression oi' a linger-lever su llieient to cause nearly one complete rotation of the corresponding displaydisk is permitted before said segments engage, respectively, the point of the radial arms 22 22 and force the latter upward against stops 1D' 19, thereby locking said disk, and consequently checking further depression o'f said inger-lever, and when theyl segments of said regulators having each the next greatest radial dimension areh uppermost the depression of a finger-lever, and consequently the rotation of the correspomling display-disk, are limited accordingly, and so IIC on with respect to the remaining regulatorsegments in the entire series. Therefore a corresponding effect is had upon the temporary display-disks 46 46 46 through the medium of the gravity-arms 48 4S 4S when any one of the finger-levers is depressed, the corresponding gravity-arm being lifted accordingly and held against any return movement by means of the spring-catch 52, de-

signed to engage the same. The required number of units having been thus displayed at the opening 38 and at the opening opposite the corresponding temporary display disk and the depression of lever 10 having resulted in forcing stem 43 downward upon the forward end of lever 43, thus unlocking' the cash-till and allowing springs 54 to urge the same outward, the user releases lever 10, which returns to its normal position through the action of spring 3l, thus permitting the remaining parts, excepting gravity-arm 48,to return each to its normal position. Having nowr placed the required number of units in the cash-till, the user closes said cash-till, which results in releasing device 53, engaging spring-catch 52 and disengaging said spring-catch from gravity-arm 48, whereupon the latter descends to its normal position and disk 46 is rotated backward till the cipher character is shown at the opening opposite said disk. Assuming, further, that nine units or cents were thus registered and indicated at opening 33, disk 16 will have been rotated to the position shown in Fig. 2, and catch 33 will engage the offset on sublever 23,together with the vertical stop 34. Now if it is desired to add one more unit to the number indicated at opening 38, the user grasps fingerpiece 42, draws chain 41 outward, and carries and holds the linger-piece over the numeral l on linger-lever 10, whereupon he depresses the latter. This again results in disk 16 being moved along one degree,thereby displaying the cipher character at opening 38, and by reason of such movement of disk 1G catch 33 trips sublever 23', thereby causing, through the action of rack 25 engaging drive-wheel 1S', disk 16 to move along one degree, thus presenting to view at opening 38 the numeral 1, which, with the cipher exposed at opening 38, will indicate the total number of units that the cash-till should contain. The depression of finger-lever 10 in this instance further resulted, through the action of gravity-arm 4S, in the numeral 1 being temporarily displayed at the opening in case 5 opposite the temporary display-disk 46. Now by again closing the cash-till disk 46 will be returned to its normal position, and the cipher character will be again displayed at the opening last named. If it is desired now to add ten units to the number contained result will be to move disk 16 one degree along in its rotary travel, thus displaying the numeral 2 at opening 3S', and the same numeral will appear at the opening in case 5 opposite disk 46 and there remain displayed until the cash till shall again have been closed. Other and higher amounts may be duly registered and indicated through like manipulation of chain 41 and depression of 'linger-lever 10, as will be readily understood.

Vhen desired,the cash-till may be unlocked without disturbance of the registering and indicating mechanism by simply depressing key 42", which is movable independently of finger-lever 10.

From the foregoing description of my improved register it will be seen that the same is well adapted for the purpose for which it is designed, and, further, that the same admits of considerable modification without material departure from its principles and spirit, and for this reason I do not wish to be understood as limiting myself to the precise form and arrangement of parts herein shown and described.
